Hi,
Making this change would be a backwards compatibility break, as suddenly people who have code that expects "T" and "Y" to produce false, would suddenly find their code was behaving differently.
If you still think this behaviour change is a good idea, then you should discuss it as a change in the PHP internals mailing list (http://php.net/mailing-lists.php) and then raise an RFC for the change to be made.
